## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability email-address-normalization-for-vendor-screening-50f7013d -d '<json body>'
```

Example prompt: Can you normalize this vendor email address 'Procurement+Orders@Acme.COM' — I need to know the canonical form and whether it has a plus-address tag, without sending any mail?

## When to prefer this

Choose this endpoint when you need to normalize vendor or supplier email addresses for deduplication or screening purposes and want to extract plus-address tags without triggering any email send or inbox verification. Prefer this over full email validation services when DNS-only, send-free parsing is required and when you specifically need plus-tag extraction as part of a vendor onboarding or screening workflow.

## Known failure modes

- Malformed or syntactically invalid email input returns an error or empty result
- Email addresses with unusual TLDs may yield unexpected domain normalization
- Plus tags embedded in quoted local parts may not be parsed correctly
- No inbox verification is performed, so normalization does not confirm deliverability

## How this service works

Email address normalization for Vendor screening: Normalize case and identify a plus-address tag without sending mail. DNS data only; does not send email or verify that an inbox exists.

## Output

Returns the normalized (lowercased) version of the email address, the canonical local part without any plus-address suffix, and the identified plus-address tag if present, derived purely from DNS-level parsing without sending mail or verifying inbox existence.
